` Beit known that' l; Josiirr C. 'Wnesinim Veitieen ofthejllnited'States, resident oi? Washhurm inthe county ot'i/Voodford and )State of llinoisylia-ve invented new and useul improvements in l/Vindow Structures, volf which the followingis a specification.

,This invention has reference to window structures and t-Wlias vfor its principal object to `iinprove that type oi' structure .having a head `space or head` pocket into which holthi'the upper nand lower sajshes may loe telescoped; whereby to leave a tree and unobstructed windowopening.

' The inyention has for a further object means for latching the upper sasliin nor malwpositionyin Athe window casiiigjand ineansonthe lower sash for releasing said latchingnieansupon the raising of the lower sash, whereby it is made possible tomteley scopebothsaid sashesintothe head space or pocket,`or tolower the upper sash in parallel relation tothe "lower sash. A further object of the invention is to provide latching means to hold the upper sash in its normal position' in the casing, which comprises ylatch members pivotally held in lopposite'sides ofthe window easing and vieldeble means for `holding said latch meinnel'rsjin locking position; Hsaidj latch member cooperating Y with complementary means onthe upper sash, and .means being "rovidfed on the lower ezftsh to releaee :said Latch `:members Aon the raising of the lower sash. v

Secured to the eupper edge of the top sash `10 is a ,head piece 14 which 1projectsflorward of said,sashininanner seen in Figure 1,( crossing `the parting `head 5 and entends across'the stile in which the lower sash 9 lslides. This head, piece 14,*whenltheupper sash, `is in its germe-l position Serres es, f1 head iframe lfor the. casing and together with the. cross piece 6 givesjthe properiinjsh to the casing andflpresents aeonipletedappearance when viewing Athe casi/ng and seelies from thewinside. The opposite ends of the headpiecel are beveled, as at l5, lsee Figures 2 and 3Eor purposes to `loe dex planed- Secure@ in endo-tothefrflfte beads 5,Y et a .point in :the-@218mg in, the rear '0f threfeross corresponding to the normal position or' the top rail oi' the upper sash 10, are latch retaining housings 1G. rlhese housings are preferably upstanding elongated U shaped metal strips which are held in place by screws 17, see Figure 4 and the upper ends ot said housings are closed by bent metal head strips 18 which overlie the upper Jfront open ends oli wid housings, as shown, which act as stops tor the latches. The latches are designated 18 and are substantially up` standing U shaped members bent into form from sheet metal and are inverted in relation to the housings and pivoted therein, at their lower ends by means ot pivot rods 1%) and carried around these rods are flat spring members 2O with ends bearing, respectively, against the latches and the inside rear wall or the housings, see Figure ll, and act to nor mally hold the latches projecting` outwardly from the housings, at an inclination, as shown; their outward movement being limited by the head strips 1S, as will be understood. The upper liront walls of the latches re inclined rearwardly to present sloping surilaces 21 and at the base oi said sloping surfaces slots 22 are provided, extending transversely oic said latch members to receive complementary embers on the upper sash to loch or hold the saine in normal position. When the latches 18 are in locking position the inclined positions in which they arc held present oppositely inclined surfaces, the tapered sui-racc 21 and the main surface of the latch which is inclined in relation to the front wall of the housings, and also provide sloping surfaces on which the coacting means, to be described, of the upper and lower sashes may ride when the upper sash is imwed to locking position and when the lower sash is moved to release the latches.

To the opposite lower ends oil the head piece la are connected plates 23 which project beyond the lower sloping ends 15 oi said head piece and are adapted to enter the slots 22 in the latches to lock the upper sash in its normal position. To the opposite ends ot the top rail 9 are connected angular plates 23 which are acapted to rioe against the latches when the lower sash is raised, to release the latches from the plates 23 on the upper sash.

Reference being had to Figure 1 it will be seen that the angular plates 23 normally overlie the lower rail 10a of the upper sash but without a binding` eil'ect on the iront tace oia said upper sash when the lower sash is raised. rlhese overlying plates have for their purpose to insure the upper sash being drawn downward from the head space or pocket C, on lowering the lower sash.

ln operation, assuming that the sashes 9 and 10 are in their normal position, shown in Figures 1 and 2 and it is desired to telescope both said sashes into the head space of pocket C to leave an unobstructed opening throughout the window casing, the lower sash 9 is raised bringing the angular plates 23 into contact with the latches and said plates riding over their iront liaces will cause the same to be moved bach into the housings, or from the dotted line position in lligurc l1- to the 'full line position in said figure and Figure 3, which movement will release the latches from the locking plates 23 on the sash 10. On the release of the locking plates on the upper sash the releasing plates on the lower sash have been moved up into position with the angle of the plates 23 disposed between the beveled ends et the head piece 1d and the casing of the window. The Jfurther upward movement of the lower sash, having a bearing as it will with the head piece let on the upper sash, will cause said upper sash to be raised with the lower sash into the head space or pocket C, as shown in dotted lines in Figure 1. To lower the upper sash 10 to a position behind the lower sash, within the window casing, the latches are released in the manner just described when the two sashes may be lowered to the position desired in the casing. As will be obvious, the latches serve as locks to secure the upper sash in the casing, which however, need not dispense with the usual sash locks.

rllhe hardware provided, as will be seen, is of the simplest form yet practical and etlicient and may be produced at the lowest possible cost.

llhat I claim is 1. In a pocket window structure, in combination, an upper and a lower sash adapted to be telescoped into the pocket of the window, a head piece connected with the top rail oi' the upper sash and overlying and adapted to be engaged by the lower sash when raised, latch members pivoted to the window casing, means to yieldingly hold said latch members in locking position, complementary means on said head piece arranged to have a locking engagement with said latch members, and means connected to the lower sash arranged to have a slidable relation with said latching members for releasing the same when the lower sash is raised.

2. In a window structure and in combination with the upper and lower sashes, of means for locking the upper sash in normal position and for releasing said locking means by and with the raising of the lower sash, comprising housings for securement in the window casing, yieldable latches pivoted in said housings, plates on the upper sash arranged to have a locking relation with said latches, and angle plates on the lower sash adapted to have a slidable relation with said latches when the lower sash is raised, whereby to release said latches.

Sil

llo

on the lower sash to release said locking means during the raising of the lower sash and for drawing down the upper sash from the pocket when lowering the lower sash.

In witness whereof, I have hereunto afffxed by hand this 24th day of November JOSEPH C WEGSTEIN.
